Analysis of stellar populations with large empirical libraries at high spectral resolution
Philippe Prugniel, Mina Koleva, Pierre Ocvirk +2
The stellar population models dramatically progressed with the arrival of large and complete libraries, ELODIE, CFLIB (=Indo-US) and MILES at a relatively high resolution. We show…
Comparison of different spectral population models
Mina Koleva, Philippe Prugniel, Pierre Ocvirk +3
We have compared simple stellar populations (SSPs) generated with different population synthesis tools: BC03, Vazdekis and Pegase.HR and different stellar libraries: ELODIE3.1, Ste…
Age and metallicity of Galactic clusters from full spectrum fitting
Mina Koleva, Philippe Prugniel, Pierre Ocvirk +1
We are using full spectrum fitting to determine the ages and metallicities of Galactic clusters (M67 and globular clusters). We find that the method is very accurate to measure the…
A Compact Cluster of Massive Red Galaxies at a Redshift of 1.51
P. J. McCarthy, H. Yan, R. G. Abraham +15
We describe a compact cluster of massive red galaxies at z=1.51 discovered in one of the Gemini Deep Deep Survey (GDDS) fields. Deep imaging with the Near Infrared Camera and Multi…
The Gemini Deep Deep Survey: VIII. When Did Early-type Galaxies Form?
Roberto G. Abraham, Preethi Nair, Patrick J. McCarthy +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys (Ford et al. 2003) to measure the cumulative mass density in morphologically-selected early-type galaxies over…
